During wind turbines operation, yaw and pitch bearings suffer from sequential traction-compression stresses causing millions of micro movements per cycle between the gear teeth. This situation reduces the lubricant thickness ...

Paper-based microfluidics devices can create a new healthcare model. Cellulose is carbohydrate polymer biocompatible and hydrophilic. These characteristics enhance the development of user-friendly diagnostic devices, but ...

A novel type of spiral micromixer with expansion and contraction parts is presented in order to enhance the mixing quality in the low Reynolds number regimes for point-of-care tests (POCT). Three classes of micromixers ...

Resulta un hecho común que en fiestas tradicionales y populares se concentre un gran número de personas en recintos abiertos de dimensiones limitadas, incluso en estos casos de recintos abiertos, son frecuentes situaciones ...

Microfluidic paper-based analytical devices (µPADs) are leading the field of low-cost, quantitative in-situ assays. However, understanding the flow behavior in cellulose-based membranes to achieve an accurate and rapid ...

Actualmente, más de una tercera parte de los tipos de papeles que hoy empleamos son para nuevos usos que hace diez años no existían. Además, la demanda creciente de productos basados en materias primas renovables y la ...

Skin models offer an in vitro alternative to human trials without their high costs, variability, and ethical issues. Perspiration models, in particular, have gained relevance lately due to the rise of sweat analysis and ...

In this paper, an uniplanar RF-MEMS second-order bandpass filter with reconfigurable centre frequency is presented. It is based on half-wavelength slotline resonators, which are loaded using RF-MEMS switches connected ...

Radio frequency microelectromechanical system (RF-MEMS) switches have demonstrated superior electrical performance (lower loss and higher isolation) compared to semiconductor-based devices to implement reconigurable microwave ...
